Re: 2.6.5 and "Badness in pci_find_subsys"
I found that using the 333MHz setting for ram (instead of 400MHz), stopped the system from crashing. (I use certified twin-packed dual chanel 400MHz 256MB dimms).
I still get random pci_find_subsys errors, but the system doesn't crash.
I've also read somewhere that setting the onboard GPU to use 128MB shared memory might help. I haven't tried this myself.
